16. Magnesium has a density of 1.74g/cm3. A strip of magnesium metal measures 0.104m long and is 2.52mm wide. If the mass of the strip is 0.104 g, what is the thickness of the magnesium strip

228.1 m

Explanation:

Area of the magnesium strip = 0.104m  * 2.52 * 10^-3 = 2.62 * 10^-4 m^2

Density of Magnesium strip = 1.74g/cm3

Mass of magnesium strip = 0.104 g

But

density = mass/ area * thickness

density * area * thickness = mass

thickness  = mass/density * area

thickness  = 0.104 g/2.62 * 10^-4  * 1.74

thickness  = 0.104 g/ 4.56 * 10^-4

thickness  =  228.1 m

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
